The Scolecophidia, commonly known as blind snakes or thread snakes, are an infraorder of snakes. They range in length from 10 to 100 centimeters (4 to 40 inches). All are fossorial (adapted for burrowing). Five families and 39 genera are recognized. The Scolecophidia infraorder is most-likely paraphyletic (with the family Anomalepididae recovered with strong support as sister clade to the 'typical snakes').
